There I was, staring into my pantry, feeling that familiar weeknight panic when dinner feels like a riddle wrapped in a mystery inside an enigma. The wind was howling outside, a sure sign that life demanded something warm and comforting. And then my eyes landed on a bottle of Marsala wine and a bag of onions that had seen better days. That’s when it hit me: French Onion Marsala Soup. It’s like a classic French onion soup but with a hint of Italian flair thanks to the Marsala. Imagine the deep, caramelized onions mingling with the rich, sweet notes of the wine. It’s as if France and Italy had a cozy dinner together and decided to share. This dish is perfect for those chilly evenings when you crave something satisfying yet sophisticated.

What You’ll Need

The beauty of this soup is its simplicity. Chances are you already have most of this on hand. Here’s what you need to gather:

• 2 tablespoons of butter
• 1 tablespoon of olive oil
• 6 large onions, thinly sliced
• 4 cups of canned beef broth
• 1 cup of Marsala wine
• 1 teaspoon of dried thyme
• Salt and pepper to taste
• 1 teaspoon of sugar
• A handful of Texas toast croutons
• 4 slices of provolone cheese
• 1 cup of diced Swiss cheese
• 1/2 cup of grated Parmesan cheese

How to Make French Onion Marsala Soup

1. Start by melting the butter with the olive oil in a large pot over medium heat. You’re looking for a little sizzle but not a full-on fry. Add the onions and stir them continually. Your goal is to achieve that beautiful translucency, where they look like they’re almost see-through but with a hint of golden edges.
2. Once your onions are ready, pour in the beef broth, Marsala wine, and add the thyme. Let that mixture simmer for 30 minutes. This is where the magic happens, and your kitchen starts smelling irresistible.
3. Time to sweeten the deal! Add the sugar and season with salt and pepper. Be judicious with the salt, as the cheese and beef broth bring their own saltiness to the party.
4. Ladle the soup into oven-safe bowls. Now for the fun part—place a handful of croutons in each bowl. Sprinkle on some Parmesan and Swiss cheese, then lay two slices of provolone on top, letting them drape over the sides of the bowl.
5. Carefully set the bowls on a cookie sheet (just in case of overflow) and broil in a preheated oven until the cheese bubbles and turns a glorious golden brown. This will only take a few minutes, so keep a close eye to avoid burning.

Cook’s Notes

You’ll want to take your time caramelizing those onions; it’s the bedrock of flavor in this dish, so resist cranking up the heat in impatience. If you’re making this ahead, stop just before you top the soup with croutons and cheese. Store the soup in the fridge for up to three days, then reheat and finish under the broiler. Leftovers can be kept for another day or two, although the onions may soften further, making the soup even more flavorful.

Make It Your Own

• Not a fan of provolone? Swap it out for Gruyère to up that gooey, nutty goodness.
• For a vegetarian twist, use vegetable broth instead of beef broth and maybe a splash of balsamic vinegar for depth.
• Want a bit more texture? Add some sautéed mushrooms along with the onions for an earthy touch.
• If you’re gluten-free, forgo the croutons and add a thick slice of gluten-free bread right before broiling.
